Purion 200 should be mounted next to the left handle. The plus/minus buttons should be aligned vertically. This way you can easily reach the buttons and have optimum display readability at the same time.
Please note when aligning the display:
Loosen the clamping screw before aligning.
When aligning the Purion 200, grip it on the left in the area of the clamps/buttons and not on the right in the area of the display.
Avoid collision with fixed components (e.g. brake clamp).
